American tourist
I love this film, but hate the way they portray the American tourist in the bar. They have this nerdy, over-optimistic fool (dressed like a moron) enter the bar, and ask if he can use the bathroom in the most naive manner.
The boys of course hear this clueless yank's request and take it upon themselves to beat him up and take his money. Fairly predictable character writing of an American by a UK writer.
Folks, please don't get the idea we Americans are all like this. We're a large country with many many types of people and personalities...just in case you're gullable enough to buy what films are selling.
